MANUFACTURE OF JUG-TOPS.

SPECIFICATION forming part of Letters Patent No. 447,502, dated March 3, 1891 Application filed April ll 1890. Serial No. 347,501. (No model.)

To all whom it may concern:

Be it known that I, HOMER WRIGHT, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of J ug-Tops, of which the following is a full, clear, and exact description.

In the accompanying drawings, Figure 1 is a vertical sectional View of a blank which has been operated on according to the first step of my improved mode of manufacture. Fig. 2 is a similar view showing the condition of the blank when the center of the bottom has been punched out. Fig. 4 shows in section the blank after punching out the entire bottom and forming the bead 5. Fig. Sshows in section the dished ring punched out from the bottom. Fig. 5 shows in section the blank after the ring has been forced into place. Fig. 6 shows in section the blank after the lip or spout has been applied. Figs. 7 and 8 show in perspective the blank before and after the application of the thumb-piece. Fig. 9 shows in vertical section the completed jug-top.

The complete jug-top, as shown in Fig. 9, comprises a collar A, and a lid B, hinged to the collar. The collar consists of several parts, a spout 6 and a drip-trough formed by a portion 3 of the collar, and an annular ledge 2 at the base of the part 3.

In making the collar of the jug-top I first take a sheet-metal disk or plate, and by means of dies of usual kind, the construction of which will be understood by those skilled in the art, I draw it into the shape shown in Fig. 1. The blank is then a cup, having at the bottom a portion 2 in the form of a frnstumot' a cone, at the top a flaring portion 3, and an intermediate cylindrical portion 1. I next take the blank of Fig. 1 and punch out the fiat bottom portion of the part 2, thus bringing the blank into the form shown in Fig. 2. I then cut out from the bottom of the blank of Fig. 2 the annular conical or dish-shaped portion 2 shown in Fig. 3, and by means of suitable tools, such as are well known in the art, I form an internally-projecting beadorshoulder 5 around the blank at the juncture of the parts 3 and 1. I then place the part 2 within the blank, so that it shall fit against the under side of the bead 5, and subject it to lateral compression to flatten it out from its dish Small holes are then punched in the ring 2,

and the lip or spout portion 6 is applied thereto, tongues 7 on said spout being fitted into the small holes in the ring and clinched, in order to hold the spout in place. The part 3 of the blank opposite the spout is then out out, so as to afford a slotted portion b for the thumb-piece of the lid and opposite points 0 for the spring. A spiral spring 8 is then applied, as shown by dotted lines in Fig. 7, the points 0 fitting within the ends of the spiral, one end of the spring being left free and the other end being soldered to the blank. The

thumb-piece 9 is then applied to the blank,

the rear end being passed through the slot 1), and bent up over the points a and over the interposed spiral spring, the free end of which spring fits in a notch at the end of the thumbpiece, as shown in Fig. 8. The thumb-piece is then passed through a slot at the edge of the lid 10, and is soldered to the lid, the thumbpiece thus forming the pintle on which the lid turns and dispensing with the use of a separate wire for that purpose. The jug-top is then completed and is ready to be applied to the jug.

From the foregoing description it will be seen that the mode of manufacture which I employ is very simple and economical, and the jug-top which is formed thereby possesses many desirable qualities of neatness, durability, and oh eapness. The fact that the part 2 is secured in place without the necessity for soldering results in a saving of cost, which in the aggregate is very considerable. It will be understood that the method of manufacture may be varied somewhat within the limits of my invention. For example, I do not desire to limit it to the precise order in which the steps are performed nor do I desire to limit the broad claim relative to the attachment of the part 2 to the cutting outof this ,part from the body of the blank, though the formation of such piece from the material of the blank is economical and desirable in many respects, and I intend also to claim it herein.

I claim- 1. The method hereinbefore described of forming a jug-top, which consists in forming an annular body portion, placing within the same a dished ring or disk, and flattening said ring or disk, whereby it is expanded and firmly secured in place, substantially as and for the purposes described. M

2. The method hereinbefore described of forming a jug-top, which consists in forming an annular body portion, forming therein an internally-projecting head or shoulder, placing against said bead or shoulder a dished disk or ring, and flattening the disk or ring, whereby it is expanded and firmly secured in place, substantially as and for the purposes described.

3. The method hereinbefore described of forming a j ug-top, which consists in forming a cup-shaped blank having a dished bottom, cutting out the middle of said bottom and the annular rim 2 thereof, and securing the annular portion within the blank by expanding it therein, substantially as and for the purposes described.

4. The method hereinbeifore described of forming a j ug-top, which consists in forming a cup-shaped blank, cutting out and separating the middle of the bottom and the annular rim thereof, and securing the rim within the blank, substantially as and for the purposes described.

5. In a jug-top, the combination of a collar having a cut-out portion 6 with opposite integral projections c, a spiral spring interposed between said projections and held thereby, a lid, and a piece which is secured to the lid and which passes around the projections and spring and forms the pintle of the hinge, substantially as and for the purposes described.

6. In a jug-top, the combination of a collar having a cut-out portion 7) with opposite integral projections c, a lid, and a spiral spring interposed between the projections and bearing on the lid and spout, substantially as described.

In tcstimony whereof I have hereunto set my hand this 9th (lily of April, A. D. 1890.
